FASTENING DEVICE.

Application filed June 28, 1920.

To all whom it may concern:

Be it known that I, FRANCES C. McDoN- ALD, a citizen of the'UnitedStates, and a resident of Chicago, in the county of Cook, State ofIllinois, have invented certain new and useful Improvements in FasteningDevices, of which the following is a specification, reference being hadto the accompanying drawings.

My invention relates to fastening devices of a type adapted either togrip a button connected permanently with the device, as in the case of ahose supporter, or to grip a button mounted upon the part to be fastenedindependently of the fastening device as is common in childrens clothes,in corsets, in Supporters of various types, in curtain mountings, and inmany other well known instances. Devices of this type have heretoforebeen produced involvin the use of keepers held yieldingly in position bythe resiliency of the device for preventing the withdrawal of the buttonfrom the engaging member, but such devices have not come into generaluse, so far as I am aware, and it is the object of my present inventionto provide a new and improved form and arrangement of parts by which Iam better enabled to obtain my desired results, by which the device ismade stronger and more serviceable, by which it can be more readily andeasily manipulated, and by reason of which it can be more cheaply andeasily-produced in large quantities. The preferred means by which I haveaccomplished my objects is illustrated in the drawings and ishereinafter specifically described. That which I believe to be new anddesire to cover by this application is set forth in the claims.

In the drawings,

Figure 1 is a front face view of my improved fastening device mountedupon a supporting strap and engaging a button carried by a garment to besupported;

Fig. 2 is a horizontal section taken on line 2-2 of Fig. 1;

Fig. is an end view of the device of Fig. 1 as seen from below in saidfigure;

Fig. 4 is a view similar to Fig. 1, but partly in section, and with thedevice c0llapsed by pressure upon its sides for releasing the keeper;

*ig. 5 is a horizontal section taken on line 5-5 of Fig. 4; and

Fig. 6 is a side view of my improved Specification of Letters ratent.

fastening device as applied to a hose supporter.

Referring to the (ll'iLWlI'lgS in which corresponding parts areindicated by the same reference characters,10 indicates the operativeend portion of an engaging loop which in the construction illustrated isin the form of a wire bent intothe shape of a letter U. A wider portion11 of such loop is produced by the provision of offsets 12 in the sidesof. the loop, such offsets be ing directed diagonally outwardly and backwardly from the plane of the end portion 10 as will be appreciated by aninspection of Figs. 1 and 6. As is shown'in Fig. l, the sides of thewider portion 11 are substantially straight and parallel with eachother, being provided at their upper ends with outwardly-extending arms13. The arms 13, in turn, are provided with inwardly-extending arms .14:which extend into overlapping position within a sleeve 15, as is bestshown in Fig. 4.

A U-shaped keeper comprising arms 16 and a cross-bar 17 is pivotallymounted upon the outwardly-extending arms 13, of the loop member bymeans of eyes formed upon the arms 16 as is best shown in Fig. 6, thekeeper being adapted to swing between a raised position as shown in Fig.6 to a position in engagement with the loop as shown in the remainingfigures. As is best shown in Fig. 6, the arms 16 are deflected at thepoint 18 adjacent to the cross-bar 17, whereby the said cross-bar willnot interfere with the movement of the keeper into position to clasp theloop yieldingly at a point adjacent to the off-sets 12. as is clearlyshown in Figs. 1 and 2. As is best shown in F ig. 2 the cross-bar 17 isprovided with a projecting lip 19 by which an operator can obtain a holdupon the keeper for swinging it out of gripping position.

As shown in the several figures of the drawings the loop member of myfastening device is secured in position by stitching at the lower end ofa strap 20 which extends about the sleeve 15. In Fig.1 the operative endportion 10 of the loop is shown in engagement with a button 21 mountedby means of stitches upon a garment 22 a fragmentary portion of which isshown. In this figure the keeper is shown in operative position with thecross-bar 17 preventing the withdrawal of the button from the engagingloop, the keeper itself being held yieldingly in position by itsengagement with the sides of the loop. When it is desired to release thefastening device from the button 21, pressure is applied to the sideportions of the loop member at 28 for eompressin or collapsing suchmembers as is shown in ig. 4 for moving the sides oi the loop out ofengagement with the keeper. The operator is then enabled very easily bymeans of the lip 19 to lift the keeper out of its operative position soas to permit the button to be moved upward with respect to the loopmember into position to be withdrawn through the wider portion 11 of theloop.

In Fig. 6 the strap 20 is provided with a supplemental strap orsupporting part 24 which is provided at its lower end with a buttoncomprising a shank portion 25 and a head portion 26. Inasmuch as thisarrangement of parts is well known in the art, it is believed to beunnecessary to describe the same further in detail herein.

So far as Lam aware I am the first in the art to provide a fasteningdevice in the form of a loop comprising a narrow operative portionadapted to engage the shank of a button and a wider portion provided byreason of laterally-disposed offsets in the sides of the loop, with akeeper adapted to be held yieldingly in position across the loopadjacent to the offsets for preventing the withdrawal of the button fromthe 0 erative end portion of the loop; to provi e a keeper adapted to beheld yieldingly in position across a loop adjacent to offsets in theside of the loop, such keeper being pro vided with a projecting lipextending at an angle with respect to the body of the keeper; or toprovide a construction involving beveled overlapping ends of armsinclosed in a sleeve and adapted to be moved inwardly with respect toeach other as is shown in Fig. 5. My claims are accordingly to be givenan interpretation for assuring me protection in the use of thesefeatures.

What I claim as my invention and desire to secure by Letters Patent, is-

1. A fastening device 01 the class described, comprising abutton-engaging member formed from a piece of wire bent at its centralportion to form a loop at the lower end of such member and having itssides bent to form offsets that are directed outwardly and backwardlyfrom the plane of said loop, in combination with a keeper formed from apiece of wire pivotally connected with said. first-named member and bentinto an approximate U-shape, the lower portion of the arms of the keeperbeing turned outward to permit the cross-bar member of the keeper to liebeneath the offsets in said button-engaging loop and the lower parts oithe arms of the keeper to lie partially behind the sides of thebuttonengaging member.

2. in a fastening device of the class described comprising abutton-engaging member formed from a piece of wire bent at its centralportion to form a loop at the lower end of such member and. having itssides bent to form offsets that are directed outwardly and backwardlyfrom the plane of said loop, in combination with a keeper formed from apiece of wire pivotally connected with said first-named member and bentinto an approximate U shape, the lower portion of the arms of the keeperbeing turned outward to permit the cross-bar member of the keeper to liebeneath the ottsets in said button engaging loop, and the r-traightlower parts of the arms of the keeper and their outwardly-turnedportions lying, respectively, partially behind the arms of thebutton-engaging member and the said offsets that are formed therein.

A. fastening device of the class described, comprising a button-engagingmember formed from a piece of wire bent at its central portion to form aloop at the lower end of such member and having its sides bent to formoffsets that are directed outwardly and backwardly from the plane ofsaid loop, in combination with a keeper formed from a piece of wirepivotally connected with said first-named member and bent into anapproximate U-shape, the lower portion of the arms of the keeper beingturned outward to permit the cross-bar member of the keeper to liebeneath the offsets in said button-engaging loop and the lower parts ofthe arms of the keeper to lie partially behind the sides of thebutton-engaging member, said cross-bar member of the keeper beingcentrally bent to provide a forwardly-projecting lip for engagement by afinger of the user when swinging the keeper out of operative osition.
